Description

When punching a nether portal block inside of a nether portal frame, the portal blocks did not disappear.

What I expected to happen was...:
for the nether portal blocks to disappear.

What actually happened was...:
Just that one single block was destroyed, but the other parts remained active, and did not disappear.

Steps to Reproduce:
1. Create a nether portal of any size.
2. Enter the nether portal.
3. Attempt to destroy the naturally spawned nether portal by "punching" the nether portal block, not the obsidian.

MC-48925When a creeper explodes my nether portal it doesnt explode the whole portal (the purple stuff) it just destroys part of it. How to reproduce. spawn a creeper next to a nether portal. then make it explode. It should not explode the whole portal.
